I have a Sony Xperia z5 premium dual.
The problem is that two days ago I noticed something weird, there was another image showing up on the screen, it's like the phone is taking screenshots every minute and showing it on the screen but just slightly visible.
Is it a bug or something?
Hi @Aragor, sorry to hear about this. 
Would it be possible for you to provide me with a screen shot of this "overlay"? That would be really good as I would be able to see what the overlay looks like.
To take a screen shot, simply press the power button and tap on "Take screenshot" and upload it here.
You can also make sure that you have not enabled the developer options in the device. You can see this if you go to Settings > Developer options, if this is enabled, try turning it off and see if the overlay is gone.
Let me know how it goes!
Hi
Checked the developer mode, it wasn't on.
Took an screenshot but the overlay is not visible in the picture but I included the screenshot,
It's mostly noticeable in notification bar and in some apps
I managed to capture the overlay it's slightly visible, mostly the upper part
